Azimuth Propulsion

Azimuth propulsors have, due to their superior manoeuvrability and operational versatility, become the propulsion norm for various ship types. The agility expected in ship-assist tugs or the novel operation modes of most modern icebreakers, like ice-milling and ice management, can only be achieved with azimuthal propulsion units.

To ensure safe and efficient operations, Steerprop propulsion units always include our condition monitoring system, Steerprop Care, as a fully integrated part of the delivery.

Steerprop CRP and CRP ECO


Steerprop contra-rotating propellers (CRP) in a push-pull configuration are specifically designed to meet the toughest customer needs. We combine the outstanding manoeuvrability of azimuth propulsors with the excellent efficiency of our CRP technology. CRP technology allows vessels to operate under demanding conditions where high fuel efficiency is a critical factor. The design has been tested and verified in action worldwide for decades.

  • Dual-end push-pull contra-rotating propellers
  • Power range from 900 to 3,500 kW and CRP ECO from 5,000 to 15,000 kW
  • Z-drive or integrated permanent magnet motor drive
  • Applications: vessels with demand for high comfort class, good fuel economy with or without ice
    class and icebreakers
  • SP CRP is ideal for ferries, offshore vessels and merchant vessels
  • SP CRP ECO is also ideal for cruise vessels, as well as icebreakers and high ice class vessels.

Main benefits

  • High manoeuvrability
  • Light load on propellers, resulting in:
    • Good cavitation performance
    • Low noise and vibration levels
    • High efficiency
  • Low emissions due to good fuel economy
  • Higher bollard pull / DP-thrust compared to single open propeller
  • Effective ice milling with pulling propeller
  • Best ice management with propeller wash.

Steerprop PULL


Dependability is especially critical in harsh arctic environments. The Steerprop ARC arctic azimuth propulsor line has been designed and built with multiple layers of redundancies and fail-safes for reliable, efficient and safe operations in the most extreme operating conditions. These advanced propulsors combine ice-breaking power with the reliability of mechanical construction and the accurate controls of modern automation technology.

  • Selected models available up to 12,000 kW (depending on ice class and application requirements) in the most demanding polar ice-classes
  • Pulling open propeller
  • Applications: vessels with high ice class and icebreakers

Main benefits

  • Pulling open propeller
  • Effective ice milling
  • Good ice management with propeller wash
